The origin of the Xq21.3/Yp regions of homology in Homo sapiens by a reduplicative translocation dated at between 3 and 2 million years BP and a subsequent (and presently undated) paracentric inversion that split the translocated block on a hominid Y short arm. Adapted from Schwartz A. et al (Reconstructing hominid Y evolution: X-homologous block, created by XY transposition, was disrupted by Y...

The acronym VACTERL describes the non-random co-occurrence of three of the following anomalies: vertebral (V), anal (A), cardiac (C), tracheoesophageal fistula with or without oesophageal atresia (TE), renal (R) and limb defects (L). Here, we report a newborn baby with VACTERL-type anomalies along with a single umbilical artery. The additional interesting findings include development dysplasia ...

We present .a study of the decay sequence J/w + yX, X-+ yp', p "-+ rr+rr-, _. based on 5.8 x lo6 produced J/i) collected by the Mark III detector at SPEAR. In the yp " mass spectrum, we find two peaks with masses and widths consistent with the axial vector mesons ji(1285) and ji(1420) that have recently been observed in two-photon collisions. Fits to the angular distributions confirm that the f...

A review of the latest measurements of the primordial abundances of the light nuclei D, He, He and Li is given. We discuss in particular the primordial abundance Yp of He as measured in blue compact dwarf galaxies. We argue that the best measurements now give a “high” value of Yp along with a “low” value of D/H, and that the two independent measurements are consistent within the framework of st...

A reanalysis is made for the helium abundance determination for the Izotov-Thuan (2004) spectroscopic sample of extragalactic H II regions. We find that the effect of underlying stellar absorption of the He I lines, which is more important for metal poor systems, affects significantly the inferred primordial helium abundance Yp obtained in the zero metallicity limit and the slope of linear extr...

In this issue of the EMC Magazine, you will find a preview Young Professional (YP) events being planned for year's Symposium in none other than “Beer City USA”: Grand Rapids, Michigan! That's rightƒ not only is THE best opportunity to learn and network with likeminded individuals, but it's hosted city where there are more 40 craft breweries within 30-minute drive, at least two which you'll have...

the deleterious effects of salinity on plant growth and development are associated with the imbalance ion in plant, decreased k+ and increased na+, and ultimately yield loss. in order to evaluate the effects of salinity, 41 bread wheat varieties (trticum aestivum l.) were planted in the randomized complete block design with three replications under two saline irrigation conditions, 0.631 and 11...

in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a  population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...
